network issue on ec2 classic us-east-1??

Grant,

We have been having issues for a few weeks now with instances that randomly stop getting their IP from DHCP. Did you see any dhcp errors?

Regards,

Dovid

Hi,

Over the last 6 hrs i have had over 100 instances in us-east-1 in EC2
Classic fail their instance health checks and a reboot via the console
solves them.  Logs on the host point to a loss of all network
connectivity.  Anyone else experiencing something like this?

Reached out to AWS support and haven't gotten anywhere with that yet.
